Product details
Overview
ADSP-21062LKBZ-160 from Analog Devices is a 32-bit floating-point SHARC® digital signal processor with 2 Mbit dual-ported on-chip SRAM, 40 MHz instruction rate (25 ns cycle), and 80 MFLOPS sustained performance. It integrates serial ports, six link ports, host interface, DMA controller, and JTAG emulation for real-time signal processing in communications infrastructure and radar systems.
For engineers reviewing the ADSP-21062LKBZ-160 datasheet, ADSP-21062LKBZ-160 pinout, ADSP-21062LKBZ-160 application, or ADSP-21062LKBZ-160 equivalent, key selection criteria include 3.3 V core operation, 225-ball PBGA package compatibility, dual-ported memory bandwidth, and glueless multiprocessing support via link/external bus.
Technical Context
The ADSP-21062LKBZ-160 implements the SHARC Super Harvard Architecture with four independent buses enabling simultaneous dual data fetch, instruction fetch, and nonintrusive I/O. Its computation units-32-bit IEEE floating-point multiplier, ALU, and shifter-execute parallel single-cycle operations while supporting 32-bit fixed-point, 32-bit single-precision, and 40-bit extended-precision formats.
Dual data address generators (DAG1/DAG2) provide hardware circular buffering and bit-reverse addressing essential for FFT and filter implementations. The on-chip instruction cache enables three-bus operation (instruction + two operands) per cycle, sustaining full-speed execution of looped DSP kernels without pipeline stalls.

FAQ
What is the maximum operating frequency of the ADSP-21062LKBZ-160?
The ADSP-21062LKBZ-160 operates at a maximum instruction rate of 40 MHz, corresponding to a 25 ns instruction cycle time. This speed is fully supported under specified 3.3 V supply and ambient temperature conditions per the official Analog Devices datasheet Rev. H. All core functions-including multiplier, ALU, and shifter-execute in a single cycle at this rate, and the on-chip instruction cache ensures sustained 40 MHz performance for looped DSP kernels.
Does the ADSP-21062LKBZ-160 support JTAG debugging?
Yes, the ADSP-21062LKBZ-160 includes a fully compliant IEEE 1149.1 JTAG Test Access Port (TAP) with TCK, TMS, TDI, TDO, and TRST pins. This enables boundary scan testing, in-circuit emulation, and real-time debug capabilities using Analog Devices EZ-ICE or third-party JTAG emulators. The JTAG interface provides full visibility into internal registers, memory, and program flow without impacting real-time system timing during active execution.
How much on-chip memory does the ADSP-21062LKBZ-160 have, and is it dual-ported?
The ADSP-21062LKBZ-160 integrates 2 Mbit (256 kwords × 32-bit) of on-chip SRAM organized as two 1 Mbit blocks, both dual-ported. This allows simultaneous, independent access by the core processor and DMA controller-or I/O processor-in a single cycle. Memory can be configured for 16-bit, 32-bit, or 48-bit word widths, and supports 16-bit floating-point storage mode to effectively double data capacity for coefficient tables and buffers.
What package type is used for the ADSP-21062LKBZ-160?
The ADSP-21062LKBZ-160 uses a 225-ball plastic ball grid array (PBGA) package with 1.27 mm ball pitch and 27 mm × 27 mm body size. It is RoHS compliant and thermally enhanced with an exposed thermal pad. This package differs from the MQFP_PQ4 and CQFP variants in the ADSP-2106x family and requires BGA-compatible PCB layout and reflow processes.
Can the ADSP-21062LKBZ-160 interface directly with a 32-bit microprocessor host?
Yes, the ADSP-21062LKBZ-160 features a dedicated 32-bit host port supporting asynchronous memory-mapped communication with 16-bit or 32-bit microprocessors. Host access is controlled via HBR/HBG/REDY handshake signals and operates at up to the full 40 MHz core rate. The host can read/write internal SRAM and IOP registers directly, and four DMA channels are allocated specifically for host-initiated transfers-enabling low-software-overhead bootloading and real-time data exchange.
